Answer:
120 cm^2
Step-by-step explanation:
area of a rhombus is pq/2
that means that the product of the two diagonals divided by 2 is the area of the rhombus.
so that means one diagonal is 24 and one is 10, (we are given what half of both diagonals are so just multiply by 2)
now put it in the formula
24x10 = 240
now divide by 2
240/2 = 120

Answer:
A = 360
B= 180
C=270
Step-by-step explanation:
Answer:
Step-by-step explanation:
So we have the equation:
First, note that this is the same as:
Factor out a 3:
Divide both sides by 3:
Change the negative exponent into a fraction:
Multiply both sides by 3^x:
Distribute:
Let u equal 3^x. So:
Subtract 30u from both sides:
This is a quadratic. Solve using the quadratic formula. A is 1, b is -30, and c is 1. So:
Substitute:
Simplify:
Subtract:
Simplify:
Simplify:
Substitute back u:
Take the log to base 3 of both sides:
The left side cancels:
So, our solutions are:
And we're done!
Answer:
1. 0.20 m, 200 mm
2. 152 cm, 1520 mm
Step-by-step explanation:
You may be familiar with a place-value chart that names the digits of a number based on their relationship to the decimal point. It might look like ...
(units) . (tenths) (hundredths) (thousandths)
So a number like 0.2 units can be rewritten in terms of hundredths or thousandths like this:
0.200 units = 20.0 hundredths = 200. thousandths
The name that's attached depends on where you put the decimal point.
___
When the units are meters, the corresponding names are ...
(meters) . (decimeters) (centimeters) (millimeters)
1. That is 0.200 meters = 20.0 centimeters = 200. millimeters.
2. 1.520 meters = 152.0 centimeters = 1520. millimeters.
